Today, Alfresco today launches its Enterprise v4, perhaps the biggest update since they began operations. The new software comes with mobile and tablet apps, business app integrations and is loaded with social features that help users share, comment on and collaborate on content. The software is built around an open source content management system that is used by more than 2500 enterprises in 55 countries around the globe. They call it cloud connected content.

Like other social Intranet products, Alfresco users can like or follow particular content streams. Enterprise v4 has integrated connectors to Google Docs, Microsoft Office, QuickOffice, Adobe Creative Suite and Apple's iWork app. You can also publish your content to YouTube, SlideShare, Twitter, Facebook and Flickr.

Pricing for an Alfresco Enterprise subscription starts at about $25k for the typical enterprise. You can download the new software here.
